Eevee rendering images in a higher resolution than 1980 x 1080
Computing power is limited, most computers cannot deal with that size images.
You can try adding a lot more RAM or getting a more powerful GPU (again, wtih more vRAM).
5400x3600 pixels is over 9 times larger than 1980x1080, so that will need at least 9 times more resources. Remember that increasing size means exponential increase.
If your computer cannot handle that then you have to come up with different strategies, like rendering in sections and stitch the tiles together later.
Or you can try using cloud computing or a render farm.
